METHOD FOR GRAFTING AND GROWING A CONDUCTIVE ORGANIC FILM ON A SURFACE

摘要

The invention concerns a method for grafting and growing a conductive organic film on an electrically conductive or semiconductive surface, wherein film is simultaneously grafted and grown by electrochemical reduction of a diazonium salt precursor of said film on said surface cathodically polarized to a potential not less in absolute value than the electrochemical reduction potential of the diazonium salt relative to a reference electrode. The invention is useful in particular for protecting surfaces, making localised conductive coatings, chemical sensors, in the fields of chemistry and molecular biology, for making biomedical equipment and the like.
